11. Summary

Pros:
  • solid casing,
  • sensational resolution in the frame centre,
  • very good resolution on the edge of the frame,
  • slight chromatic aberration,
  • well-corrected spherical aberration,
  • low distortion,
  • excellent coma correction,
  • decent correction of astigmatism,
  • moderate vignetting,
  • efficient stabilization,
  • silent and efficient autofocus,
  • rich standard accessory kit,
  • the warranty period of three years with a possibility of prolonging it by another two.

Cons:

  • very weak work against bright light,
  • big dimensions for an APS-C/DX lens with those parameters.

To tell you the truth I wasn’t exactly eager to test the Sigma 50-150 mm OS. I didn’t fully understand a decision of inserting that device into a 70-200 mm casing and I thought it boded ill for the lens and its potential marketability. Now I have to admit I changed my mind a bit…

I think that one of the ideas behind the launch of this lens was showing that the dimensions are no restriction whatsoever. The constructors didn’t have to struggle with trying to fit the optics into a casing which is too tight for it and they could spread their wings so to speak. The results we could admire with our own eyes - in the resolution category the Sigma 50-150 mm OS can easily compete with the best ‘primes’, being one of the sharpest zooms we’ve ever handled.

In such a situation my final verdict concerning the success of this lens must be changed a bit. There are people who don’t think that small dimensions of the equipment are a crucial feature. If they happen to own an APS-C/DX reflex camera and have been pondering over buying a brand name 70-200 mm f/4.0 lens perhaps they should reconsider and include the Sigma as one of the possibilities. Why? For a similar amount of money you can get an f/2.8 instrument which can put many good primes to shame when it comes to the image resolution.
